    No matter what amp I play throgh I can hear a high frequency(maybe wavering) that cant be dialed out with tone controls that I know of.The amp is about 8 feet away and pointed right at me.Am I catching the higher frequencies coming out of the speaker straight at me and I need a beam blocker or could it be the pickups or something else?Thanks.

    That's a quiet guitar to start with, so it should be easy to trouble shoot. A 4" paper/cardboard dot taped to the back of the grill, over the center point of the speaker should be a quick & easy wasy to fond out.

    It happens on all guitars.I put a couple of layers of clear tape in front of the center point of the v30 speaker only on the outside grill.Its a avatar 2x12 with one g12h30 and one v30.Still their.It might be the nature of the celestion vintage 30 maybe?Should I do both speakers.Does it have to be cardboard on the inside of the grill?
